Just got my Kindle and one of the main reasons is that I read lots of scientific papers in .pdf format and I get tired reading from a pc/laptop screen, while printing all of them is just a crime against humanity (and my pocket).

Yeah I know I should get the DX because of the larger screen, but there is a big difference in price and I wanted a smaller device. So I bought it knowing it wouldnt be the best solution and being determined to work around any problems.
I'd like to know if other people it use it for this type of reading and what is their approach. My .pdfs are regular papers with the two columns format and the two columns is the main problem.

I tried 200% zoom and portrait mode or 150% and landscape. In portrait the fonts are somewhat small, while landscape has the problem that Shift is a bit far in order to scoll and that it needs a lot of scrolling down.

What's your preferences or what tricks do you use in order to make it easier for you?
Any advice would be appreciated

I have some pdf documents that I use from work, two column format with lots of tables and diagrams. I find the K3 to handle these documents very well. It is all a matter of preference I guess. You will not know until you get a device, or see one in Target, Best Buy or Staples.

The zoom feature built in to the K3 worked well for me as well. I was reading only a single column zoomed in, scrolling downward, and it was fine. It isn't like reading an ebook where you can change the font, line spacing and what have you, but it does work.

I am working on a program that would reflow such pdf's to fit a 6"-inch screen. Text will be wrapped, but tables and pictures will be resized. Unfortunately it is in pre-alpha phase now. I have other work to do, too. I heard some people also try to write similar software. Maybe you should wait a couple of weeks until one of such programs pops up.

I hope some solution will be found. Converting pdfs like the ones I have is not a solution for me right now.

In that case you should go for a Kindle DXG or a similar device like PocketBook 902 when it becomes available. Today's e-Ink screens are slow and not suitable for panning while reading. So you need a larger screen. BTW why is document conversion/reflow not acceptable for you?

I wanted a small device and DXG wouldnt do it for me. Also there is the price difference.

The documents I want to read are scientific papers in .pdf and with two columns format. If I send them via mail to my @kindle.com mail they convert but some words get cut off and Tables get all jammed up. It is not 100% unreadable but if in every 2-3 paragraphs you have a sentence that is not full, you lose a lot of information.

That type of conversion is not what I mean. The program that I am currently working on reflows documents in scanned/graphical form. It takes graphical lines as they are and wraps some of them around so that they fit the page width. And it understands multicolumn documents. Can you send me a sample scientific pdf so that I can test it with my program (or just post a link to it here)? I will post here the result. I need to know if the program is worth the effort. It is not complete yet.

JSWolf you are right and I don't expect miracles. However I believe things could be improved. Until now I use the 200% in portrait, reading one column, or the 150% in landscape mode reading again one column.

is that fine with u? I haven't decide the whether kindle 3 or DX yet. Is that readable for 2 column pdf in kindle 3? The main read source is pdf for me, DX should be better, however as the same reason u have mentioned, hard to decide.

I'm using my kindle3 with roleplayinggames-PDFs which are similar formated (in 2 columns with lots of grafic) i work with 150%Zoom and "nudge"-scrolling (thats shift+5_way_controller) But, i would love to have a program wich is capable of cutting the pages at the right moments.
